# --description--

Use uma instrução `else` para executar quando o tamanho do `inventory` não for maior que um. Set the `text.innerText` to say `"Don't sell your only weapon!"`.

# --hints--

A função `sellWeapon` deve ter uma instrução `else`.

```js
assert.match(sellWeapon.toString(), /else/);
```

You should set `text.innerText` to `"Don't sell your only weapon!"`.

```js
assert.match(sellWeapon.toString(), /text\.innerText\s*=\s*('|")Don't sell your only weapon!\1/);
```

A nova linha de `text.innerText` deve estar na instrução `else`.

```js
inventory = ["Naomi"];
sellWeapon();
assert.equal(text.innerText, "Don't sell your only weapon!");
```
